Observation of Odderon Exchange

Comparison of measurements of proton-proton elastic differential cross sections at the LHC by TOTEM experiment at three different center of mass energies to the measurement performed by the dzero experiment at Fermilab for the same observable in p-pbar collisions at the Tevatron energy, allows for the first time a definite observation of Odderon exchanged, as postulated from non-perturbative QCD models 50 years ago
